Client → host.

Variants

Hello

Handshake; the reply names the host, its version and protocol version.

Probe

List the plugins inside a bundle without instantiating any (used by plugin scan).

Fields

path: String

Load

Load the bundle and instantiate one plugin (plugin_id may be omitted when the bundle holds exactly one). Replies with PluginInfo.

Fields

path: String

plugin_id: Option<String>

SetParams

Set parameters by id or display name; values in display text (2.5kHz, -6dB, 30%), plain numbers, or norm:0.3. Replies with the resulting values.

Fields

params: Vec<ParamAssign>

GetParams

Current parameter values.

ListPresets

Discover presets (CLAP preset-discovery factory / VST3 program lists).

LoadPreset

Load a preset by name or load key. Replies with the resulting parameter values.

Fields

preset: String

GetState

Save the plugin’s native state. Replies with base64 bytes.

SetState

Restore native state saved earlier.

Fields

state_b64: String

Activate

Activate at a sample rate and maximum block size and map the shared-memory file.

Fields

sample_rate: f64

block_size: u32

shm_path: String

Process

Process frames (≤ block size) from slot slot; events carry sample offsets relative to the block start, sorted by time.

Fields

slot: u32

frames: u32

events: Vec<Event>

Deactivate

Stop processing and deactivate (the plugin stays loaded).

Quit

Tear down and exit.
